Mass From N Formula

The following formula is used to calculate the Mass From N. 

m = F / a
  • m is the equivalent mass in kilograms (kg)
  • F is force in newtons (N); a is acceleration in m/sยฒ (standard gravity is 9.80665 m/sยฒ)

Divide force by the applicable acceleration. For weight at standard gravity, use 9.80665 m/sยฒ; a different acceleration gives a different mass equivalent.

How to Calculate Mass From N?

The following example problems outline how to calculate Mass From N.

Example Problem #1:

  1. First, determine the total amount of newtons (N).
    • The total amount of newtons (N) is given as 67.
  2. Finally, calculate the Mass From N using the equation above: 

m = F / 9.80665

The values given above are inserted into the equation below and the solution is calculated:

m = 67 / 9.80665 โ‰ˆ 6.832 kg


Example Problem #2: 

For this problem, the variables needed are provided below:

total amount of newtons (N) = 73

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer. 

m = 73 / 9.80665 = ?
